Photos released by police on Saturday show leather-made belts linked to disposable water bottles covered in tape.

“I have not seen this tactic in the UK before where terrorists create maximum fear by strapping fake explosives to themselves,” said Cmdr. Dean Haydon of the Metropolitan Police, who’s leading the investigation.

The three men rammed into pedestrians on London Bridge on June 3 before going on a stabbing rampage at bars at nearby Borough Market. By the time the carnage was over, eight people were dead.

The belts were still attached to the men when they were killed, Metropolitan Police said.
